SPOOLING-MACHINE FOR MUSIC-ROLLS.

Application filed. March 29, 1915.

Y 10 all @07mm 'it may concern.'

Be it known that I, GEORGE IIowLnr'r Davis, a citizen of the United States, residing in the town of l/Vest Orange, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in a Spooling-Machine for Music-Rolls, of which the following is a specification.

In my prior application filed February 24th, 1915, Serial No. 10,350, I described an improved form of music roll wherein provision was made for a substitute for the usual spool of the music roll and also improved attaching devices, whereby all of the results-of present day practice in the construction of perforated music rolls are oblrained by a structure at once simple, cheap and effective.

My present application relates to a new and useful machine for spooling or winding up perforated music sheets into the forni shown in my above named prior application. The manual labor required in such an operation must be reduced to a. minimum and speed of operation is an essential to economy in the manufacture of music rolls of the type above referred to. In the modern manufacture of music rolls it is the practice to perforate simultaneously from ten to sixteen blanls or strips of paper at the same time. As these sixteen sheets come from the perforator they must for a time, retain their relative super-posed positions in order that they may pass simultaneously through certain subsequent steps in the process of manufacture. It is necessary, therefore, to leave the teu to sixteen perforated sheets in th-e form of a loosely folded over, or plicated pile, which in practice are placed in trays as they come from the perforator ready for subsequent steps in the process of manufacture as may be necessary.

In the use of the machine described in the following specification, these trays, containing the perforated sheets, are placed in suitable positions at the rear of the machine and `he bacl end of each roll is taken separately and spooled upon the machine, after which it is removed from the mandrel of the machine, the end plugs, such as described in my above named prior application, are inserted and the end fasteners attached, when the roll is ready for boxing and shipping. An enormons reduction, both in time and labor accomplished by my improvement has resulted in labor saving amounting to from four to Specification of Letters Patent.

seven operators upon the process of a single perforating machine. Not only are the above results accomplished, but the cost of production is correspondingly reduced by this cheap substitute for the old forms of wooden and paper spools.

In carrying out my invention I make use of the structure substantially as illustrated vin the accompanying drawings wherein Figure 1, is a front elevation of my improved spooling machine.

Fig. 2, is a plan view of the same.

Fig. 7, is a cross section of Fig. 6.

Smilar letters of reference refer to like parts throughout the specification and drawings.

In Fig. 1, I have shown a base 1 which may be mounted upon a table or any other suitable support. Upon this base are three upright standards 2, 3 and 4, which are provided with journal bearings 5, 6 and 7 respectively to receive the driving shaft 8. Upon the right-hand end of the driving shaft, where it projects outside of the bearing 7, is rigidly secured the crank 9; the opposite end of the shaft 8 carries a spur gear 10. In the upper parts of the two standards 2 vand 3, I provide the bearings 11 and 12, in which is mounted the mandrel 13, which carries upon its left-hand end a pinion 1-1 for engagement with the gear 10. Reference to Fig. 3 will disclose that the standard 4 is cut away as at 15, so that the mandrel 13, with the parts attached at the free end thereof, overhangs a distance greater than the ordinary width of a perforated music sheet. From the above description, it will be readily seen that the rotation of the crank 9 will be communicated to the mandrel 13.

Referring now to Figs. 6, and 7, it will be noted that the mandrel 13 is provided with a pair of diametrically opposite grooves 16 and 17, running substantially the full length of the overhanging part of the mandrel; that is, that part of the mandrel which eX- tends outside of the bearing 12. In each of these grooves 16 and 17, is mounted a reciprocating strip of metal as 18 and 19. At intervals along the bottom of the grooves 16 and 17 are located inclined cams as 20 and 21 to engage correspondingly inclined notches 22 and 23 in the strips 18 and 19. It will be seen, therefore, that when the strips 18 and 19 are given longitudinal movement in the grooves 16 and 17, they will either come within the contour vof the mandrel 13, or project outside th ereof in accordance with the direction of their reciprocation.

Looking at Fig. 6, it will be noted that movement to vthe right will cause the strips to be withdrawn into the contour of the mandrel while reciprocation to the left will cause said strips to extend beyond the circumference of the mandrel. Each of the strips 18 and 19 is connected to an end handle 24, by which said strips may reciprocate within the grooves.

About midway of the free overhanging portion of the mandrel 13, I provide a circumferential groove 25, which is in effect, a reduction of the diameter of the mandrel. One of the reciprocating strips 19, is cut away to correspond to this reduced diameter. Rigidly secured to the bottom of this groove 25 is a spring 26 held in place by means of the screws 27, so that the tendency of the spring is to hug the cylindrical portion of the mandrel. Upon the strip 19, I provide a. cam 28 Ain position to elevate the free end of the spring 26, when the strips 18 and 19 are moved to the right, but when the strips are moved in the opposite direction, the spring 26 will again grip very closely the cylindrical portion of the groove 25. In this manner, when it is desired to start a music sheet upon the mandrel the handle 24 is pulled out to the right to elevate the free end of the spring 26, so that the end of the music sheet may be inserted thereunder; the handle 24 is then pushed back into the full line position, looking at Fig. 6, when, of course, the spring 26 will grip the end of the music sheet and simultaneously the strips 18 and 19 will be extended beyond the circumference of the mandrel 13. If, now, the crank 9 is rotated, the music sheet will be rapidly wound upon the mandrel 13.

In order to properly guide the music sheet upon the mandrel, I provide the fixed vcollar 29, close up to the standard 3, upon the outside or free part of the mandrel 13, and at the opposite end I place the detachable collar 30, so that when in position the music sheet will be properly guided upon the mandrel The collar 30 is provided with a cylindrical hub 31 upon opposite sides of which are rigidly secured the two springs 32 and 33, saidl springs being so bent as to hug closely the reduced portion `34 of the handle 24, when said handle is pushed completely to the left as shown in Fig. 6. This method of securing the collar 30 to the free end of the mandrel, permits free attachment and detachment, and yet it is firm enough when in position to secure an accurate winding of the music sheet upon the mandrel 13.

In my former application above referred to, I have described the completed roll as comprising a number of convolutions of the back end of the music sheet formed into a tube with a strip of glue running completely across the sheet so as to form a comparatively rigid hollow spool body. In my present machine I provide means for gluing the last one of a number of convolutions so as to form ythis spool body upon the mandrel. In order that thisgluing step may be yquickly and conveniently formed, I provide in the two standards 3 and 4, the bea-rings 35 and 36, in which is mounted a rock shaft 37; upon the left-hand end of this projecting roclcshaft 'is rigidly secured the crank 38. Upon the shaft 37 are rigidly secured a plurality of arms 39 which hang vertically downward and carry at their lower ends a bar 40 of a length nearly equal to the width of a music sheet. The length of the arms 39 is such that when the rockshaft 37 is oscillated, the edge of the bar 40 will strike throughout its length upon the circumference of the mandrel 13, or in case of several convolutions of a music sheet it will strike upon the outer convolution.

Upon facing sides of the two standards v3 and 4 are the two ledges 41 and 42. These ledges support a long trough or tank 43, containing a liquid adhesive 44. This tank 43, as shown in Fig. 5, is in position to permit the bar 40 to normally rest within the liquid adhesive 44, so that when the shaft 37 is oscillated the bar 40 will carry upon its free edge suflicient of the liquid adhesive to lay a strip of the same upon the outer convolution of a music sheet so that as such music sheet is further wound up, said strip of ad-hesive will firmly unite the adjacent convolutions and form a tubular spool out of a portion of the music sheet itself.

In order that the inner convolutions of `the music roll may be firmly bound together, and these substitute spool bodies be of uniform size, I provide a tension device to firmly grip the body of the sheet as the same is being wound upon the mandrel, so that when the crank 9 is turned the mandrel 13 will also be turned to wind the inner end of the music sheet firmly and tightly upon the expanded mandrel. rIhis tension device leo ist

edge of the center of the bar 48 the pitman 19 is pivoted and the lower end of this pitman is connected to the foot lever 50, fulcrumed at 51 upon the floor beneath the machine. It will now be seen that a depression of the free end of the foot lever 50 will cause the moving tension bar 48 to rise to firmly grip the music sheet as 52, against the lower edge of the upper rigid tension bari, so that as the crank 9 is turned the inner convolut-ions of the music sheet are firmly wound upon the mandrel 13.

The music sheet 52 may be one of the super-posed ten to sixteen sheets as they come from the perforator. But in case the music sheets have been previously coiled up into rolls by means of the machine illustrated in my prior patent No. 968,136 suoli rolls may be mounted upon the loose mandrel 53 and wound directly from said mandrel upon the mandrel 13; the mandrel 53 is supported by a U-shaped bracket 511 projecting rearwardly from the standards 2 and 3, lying parallel to the mandrel 13.

The steps in the operation of spooling a music sheet are as follows: The back end of the music sheet is drawn forward underneath the tension bar 45, and the free edge thereof inserted underneath the spring 6, it being understood that said spring is elevated by means of the cam 28 when the handle 2l is pulled into the dotted line position shown in Fig. 6. YVhen the free end of the music sheet is properly inserted under the spring 26, the handle 24e is pushed into the full line position permitting the cam 28 to rrelease the spring 26 which firmly grips the inner end of the paper against the mandrel 13. At the same time the two strips 18 and 19 are projected from their radial slots 16 and 17 so as to increase the effective diameter of the mandrel 13. The operator then turns the crank 9 a few turns so as to lay a few convolutions of the music sheet upon the mandrel; he then oscillates the shaft 37 by means of the crank 38 to lay a strip of adhesive upon the outer convolution. He now depresses the foot lever 50 so as to firmly grip the body of the music sheet between the tension bars and 48, and then turns the crank 9 slightly so as to draw the music sheet firmly upon the mandrel so as to permit the glue, or other adhesive material, to firmly imite the last convolution with the next oncoming one. The foot lever may then be released and the winding continue until the sheet is completely wound upon the mandrel 13. The operator then removes the collar 30 by giving it a quick jerk to the right, disconnecting the springs 32 and 33 from, and at the same time pulling out the handle 24; this movement of the handle 24 carries with it the two strips 18 and 19, thus withdrawing them into their respective grooves 16 and 17,

thereby releasing the sheet from the gripping spring and reducing the effective diameter of the mandrel; otherwise it would be practically impossible to remove the tightly coiled music sheet from the mandrel. The coiled sheet upon removal from the mandrel is usually strapped with a rubber band so as to prevent the same from uncoiling, after which the end plugs are inserted and the end fastener secured, when, of course, the roll is completed. The spooling machine operator, however, has only to remove the coiled music sheet from the mandrel and start another.

The work is very quickly and effectively done so that with a little practice the operator is enabled to spool many thousands of rolls per day.

It will thus be seen that I have at once accomplished the manufacture of a cheap, effective, and economical spooling machine for the spooling of music sheets for the structure illustrated in my prior application Ser. No. 10,350.
